I lived in Philadelphia for graduate school from August 1988 to June 1991. I came back again in May 1992 for a few days to talk to my advisors. I returned in March 1993 to pick up some stuff I had stored here and move it to Saarbrücken, where I was starting a job. And I returned again in March 1995 to do two very important things: first, I saw what turned out to be may last concert by The Grateful Dead (18 March at the Spectrum), and the following Monday I handed in my doctoral dissertation. Now, for the first time in thirty years, I'm here again for a day. (Andrew Shields, #111Words, 18 June 2025)
